ATTACHMENT FOR SHOE-GRINDING MACHINES.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed October 2, 1915. Serial No. 53,815.

I '0 all whom it may concern:

Be it known that I, Tnnnox F. PEEL, a citizen of the United States, residing at Sibley, in the county of Osceola and State of Iowa, have invented certain new and useful Improvements in Attachments for Shoe- Grinding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in attachments for shoe grinding machines, and has for an object to provide a device for holding a shoe with its shank or sole presented to the grinding element.

Another object of the present invention lies in providing a device of this character, which will be constructed for ready attachment to any of the present forms of shoe grinding machines, and which will be simple in construction and operation and capable of a variety of movements to bring that portion of the shoe sole or shank requirin beveling into effective engagement with the emery wheel or other grinding element.

Reference is had to the accompanying drawings, in which similar parts are indicated by similar reference numerals through-.

out the several views.

Figure 1 is an end elevational view of a shoe grinding machine illustrating the improved attachment, partly in elevation and partly in section. Fig.2 is a front elevational view of the improved attachment. Fig. 3 is a fragmentary view of a shoe grinding machine illustrating a modified form of attachmentjand Fig. 4 is a fragmentary perspective view of a still further modified form of the attachment.

Referring more particularly to the drawing, 1 designates one side frame of a grinding machine, and 2 and 3 are bars connecting the same with the opposite side frame (not shown). Between the frames is journaled an emery or buffing wheel 4: arranged to be driven by the belt and pulley or other gearing usually employed for this purpose.

The improved attachment consists of a holder for receiving the shoe in substantially that manner shown in Fig. 1, and said holder is constructed of a pair of longitudinal walls 5 and 6, preferably beveled on their interior faces as indicated at 7 and 8, respectively, in Figs. 1 and 3, for supporting the shoe approximately parallel to a line drawn tangent center of which is formed a bearing 16 provided with a-flared upper end adapted to seat on a head 17 provided at the upper end of a post 18, upon which the yoke is swivelly supported. Encircling the post 18 is a pair of metallic or other straps l9 and 20, bentarcu'ate at their outer ends to conform to the curvature of a split collar 21, provided with perforated flanges 22 and 23, through which the reduced ends of said straps 19 and 20 are secured for binding the sections of the collar together in place to the cross bar 2 .of the main frame. The ends of the straps 19 and 20 are advantageously threaded for receiving-nuts, as shown in Fig. 1, whereby the attachment can be readily connected and removed. At its lower end the post 18 receives a strap 24-, to which is pivotally connected a rod 25, slidable through eyes 26 and 27, supported from a similar rod 28 mounted in any suitable manner in the rear cross bar 3 or other stationary part of the framework.

In operation, the holder may be used alone, as illustrated in Fig. 3, and the shoe is fitted through the same, as clearly shown in the drawings, with the shank extending over the wedge-shaped rear longitudinal wall 5, which latter forms a backing against which the grinding wheel 4: may operate to impart the required bevel. In accordance with this form of the invention the holder is supported in the hands of the operator who. moves the same to the position in Fig. 3 and imposes the required pressure. When the shoe holder is to be employed in conjunction with the other parts, the same is held between the arms 13 and 14: of the yoke and the trunnions 11 and 12 are threaded in the perforations in the end walls 9 and 10, when the same will be seen to be mounted for vertical revolution and endwise sliding in the yoke.

The post 18 may be revolved on the collar 21 about the cross bar 2 as a center, to withdraw th holder from operative engagement with the grinding wheel a after the opera.-

tion, and in order to insert a shoe for subse-' is accomplished when the post 18 and holder are returned to the position shown in Fig. 1.

The yoke carrying the holder is mounted to turn on the post 18 in order to bring either side of the shoe shank into more etfective en-- gagement with the wheel 4, and the holder itself is revoluble on the trunnions 11. and 12 to increase the pressure over the length of the shank.

Referring more particularly to Fig. 4, a modified form of the attachment is here shown to be supported in the hands after the manner illustrated in Fig. 3, or mounted in the arms 13 and 14 of the yoke 15 as in the case of the preferred form of holder shown in Figs. 1 and 2. This modified form of holder preferably consists of a solid block 30 of parallelepipedal configuration, having adjacent converging faces to provide a Wedge-shaped holder received between the body of the shoe and the shank or sole. The shoe is placed upon the block 30, as clearly shown in Fig. 4, and said block canbe retated on the trunnions 11 and 12 to bring the shank or sole of the shoe to the proper position in contact with the grinding wheel 4, and the holder 30 can be moved on the trunnions 11 and 12 laterally through the arms 13 and 14 to shift the shoe to difi'erent positions With respect to said grinding roller.

It is obvious that various modifications might be made in the herein described apparatus, and in the combination and arrangement-of parts without departing from the spirit of my invention.

I claim 2- 1. An attachment for shoe grinding machines, comprising means for supporting the shoe and having a surface for receiving the shank or sole and exposing the same to the grinding element, substantially as described.

2. A11 attachment for shoe grinding machines, comprising means for supporting the shoe provided with a wedge-shaped wall adapted to be received between the shoe body and shank or sole, and for exposing the latter to the grinding element, substantially as described.

3. An attachment for shoe grinding maincense chines, comprising a holder for the shoe 5. In an attachment of the character de-' scribed, the combination with a shoe grinding machine, of a shoe holder having a backing surface for receiving the shank or sole and presenting the same to the grinding element, and means mounted on said grinding machine for supporting said holder to be moved into and out of engagement With the grinding element, substantially as described.

6. The combination with a shoe grinding machine, of a shoe holder therefor, a yoke for swirelly supporting said holder, and means for mounting said yoke on the machine for movement into and out of operatire engagement with the grinding element, substantially as described.

7 The combination with a shoe grinding machine, of a shoe holder therefor, a yoke for swivclly supporting said holder, a post carrying said yoke, and connections between said post and the machine for mounting the same to swing and move the holder into and out of operative relation with the grinding element, substantially as described.

8. The combination with a shoe grinding machine, of a shoe holder having a wedgeshaped wall for receiving the shoe body and shank or sole and presenting the latter to the grinding element, a yoke, t-runnions support ing said holder to rock in said yoke, a post swivelly supporting said yoke, and. means for mounting said post on the machine, substantiallyas described.

In testimony whereof, I affix my signature.
